seemed to be a good choice since flv in mencoder is a "Sorenson H.263 (Flash-Videos)". I tried to play full resolution (640x480) video, but even with best optimizations video is sometimes slow. Once in a while video crashed while sound was still playing. Once every mpeg4 video didn't play, after rebooting everything is fine.

Mpeg4 and a resolution of 640x240 is a good choice. Audio is encoded as 64kbit mp3, constant bitrate. Mpeg4 with 640x480 seems to be broken while playing.
